5.15 has dropped all USB_GSPCA modules

[6by9]

Describe the bug

Mainline patch torvalds/linux@2a621b0 changed the default for USB_GSPCA from m to disabled, so all the dependent modules are no longer built.

https://github.com/raspberrypi/linux/blob/rpi-5.10.y/arch/arm/configs/bcm2711_defconfig#L803-L850 are all gone.
Whilst I could have created the PR myself, I know @pelwell has magic scripts to deal with configs :-)

I have the same problem as well. I was using an old camera that made use of the module gspca_stv06xx.ko, that disappeared with kernel 5.15

Thanks @pelwell. Not tested, but looks like it should do the intended thing, so I'll close.
